Definitions

  • the invention relates to a method for changing the format thickness of the cast strand a continuous casting in continuous casting operation, the strand below a mold on both sides with opposite roller carriers is operatively connected, in a series of roll-carrying, by means of joints are divided into adjacent segments and each Segment is adjustable in an angle to the casting, and wherein in one Starting position the entire strand guide to be changed to a uniform Production format thickness is set.
  • Format thickness change in the continuous casting during the casting operation are indispensable for production optimization. However, so far had to the casting speed for the thickness reduction or increase in thickness be temporarily reduced. This results in production losses and the entire Production process is at least temporarily unbalanced. Moreover, in the current process, only fixed, stepped format thickness change can be performed.

  • Everyone Roller carrier is arranged in a fixed frame and in several, split roller bearing segments associated with adjusting in combination stand.
  • the roller-bearing segments are hinged to each other in such a way that that each segment adjusted for itself at any angle to G fauxstrang and can be adjusted, and that for general adjustment of the roll carrier the upper adjustment is used. It can be a mechanical, hydraulic, or mechanical-hydraulic adjustment act.

  • the soft reduction " to a maximum immediately before the final solidification or the sump tip, can be a critical Deformation of the strand taking into account the casting speed as well as the steel grade off.
  • the document US 5,577,548 A discloses a method in continuous casting in a Continuous casting plant, wherein a strand after leaving the casting mold by a wedge-shaped roller gap is reduced in thickness.
  • a strand after leaving the casting mold by a wedge-shaped roller gap is reduced in thickness.
  • the strand is exclusively reduced in thickness in a region with a liquid center, wherein the segments are always set up so that the liquid tip of the center always lie in a region of the strand guide, in which the roller gap is closest to the following strand guide.
  • the invention has the object underlying a procedure for changing the format thickness of the cast strand of a continuous casting plant in a continuous Specify casting operation, in which the casting speed for the Transition process for the change in thickness is not reduced, that is, constant production and casting conditions are maintained.
  • transition length of the strand during the format thickness change is intended to Prevention of production losses are shortened comparatively. In all Transitional situations of the format thickness change should reduce the risk of breakthroughs be ensured optimal strand support.
  • a further embodiment of the method according to the invention provides that the Moving the segments at constant speed using dynamic position control is made, with a force threshold not be determined is exceeded.
  • Figure 1 shows the function of the process for a reduction in the thickness of a cast strip 9 of a continuous casting in continuous casting operation.
  • the strand 9 is below a mold 10 on both sides with mirror-image opposing roller supports 8, 8 'in operative connection, which are divided in a series of roll-carrying, by means of joints 5 to 7 coupled to each other segments 1 to 4.
  • Each segment 1 to 4 is adjustable at an angle to the casting 9.
  • the entire strand guide to be changed is set to a uniform production format thickness, as shown in the illustrated home position.
  • the format change is performed in a controlled sequence of adjustment steps of the segments 1 to 4.
  • the format thickness reduction is effected by sequential closing in the casting direction of the successive segments 1 to 4, as can be seen from the illustrated phases 1 to 4.
  • the articulated connection 5 with segment 2 inlet side is closed by nominal value.
  • the segment position for the target format - segment 2 outlet side with segment 3 inlet side is fed in a second adjustment phase, and in sequential order of similar steps, the adjustment of the segments 3 and 4 is made according to phase 3 or 4 shown
  • the force means 11 in the direction of a constriction of the cast strand 9 followed in phase 2 by the intervention of the adjusting 12 in the direction of narrowing of the strand cross section and sequentially in phase 3 and phase 4
  • the adjusting devices 13 and 14th up to the overall reduced format thickness, according to final state in phase 4.
  • An effective force monitoring monitors the adjustment. Should the force exceed a calculated threshold, then Position control switched to force control. After reaching the target position is switched back to position control accordingly.
  • the existing sump in segment 1, 2 and optionally 3 is not through interrupted the process.
  • the strand support is via the switching of position given to force control in all phases.
  • segment 2 outlet side is opened (phase 2).
  • the adjustment speed is calculated using the current casting speed, the segment length and the required adjustment as in the format thickness reduction.
  • An effective force monitor calculated over the current cylinder pressures Hydraulic adjustment, permanently controls the adjustment process.
  • position control switched in force control. After reaching the target position becomes appropriate switched back to position control.
